Robin Van Persie's World Cup has been quite disastrous.
He looks slow and his timing is off. In fact, you could put him down on the worst striker list along with Wayne Rooney, Cristiano Ronaldo, and Torres. One goal in 479 minutes is not very flattering.
RVP's best moment came off the pitch when he threw a tantrum after being substituted by Bert Van Marwijk in the Netherlands vs Slovakia match. He felt Wesley Sneijder should have been substituted. True that.
So, yes, he is overly due for a big game.
